Specification ot Letters Patent. Application filed August 22, 1910. Serial No. 578,450.

To all whom it may concern."

vBe it known that- I, Sex'mno SEKIXE, a subject of the Emperor of Japan, residing at Chicago, in the county of Cook and State .of Illinois, have invented certain new and useful Improvements in h'iphons, of which the following is a specification.

My invention relates to a siphon, and particularly to a siphon intended "for making a separation between liquids having ditto-rent specific gravities, which is suitable, for ex.- ample, :torremoving the cream, after it has risemt'rom the top of milk bottles; although it will be understood that the invention is not limited to this particular use. \Vhen a siphon is to'be so employed, it is necessary, for sanitary reasons, that all the portions of the device with which the liquid comes into contact should be made of material, such as glass, \\'lll(ll \\'lll not be chemically atl'ected by the cream, and which will not rustwhen washed, and the same is true it the device is to be used in the laboratory "for the separation of chemicals: and it is also very desir-.

'able thatthe fluid conduit should. be free from sharp corners or edges or recesses, which inake the device dillicult to keep clean. Again. it is desirable that the intake end of the'device be mnstructed so as to prevent or hinder any upward [low in the heavier liquid. when the. lighter liquid is being decanted, and that the device used for initially raret \'ing the air, so as to start the lion", should be so constructed that the decanting liquid eaunotbe drawn up into it.

The. object of my invention is to provide. a siphon combiningall of these severaladvantageous features. and, in addition, the advantages of simplicity and cheapness of construction.

'lhe inventitm, in a preferred emlnxliment, is shown in the accompanying drawing, wherein Figure l is a view showing the siphon in elevat on, the vessels in .connection with which the same is shown being in section. Fig.2 a- 'tragmentary section of, the intake end of the device; and Fig. 3 a similar view of the discharge end.

lake. characters of reference indicate like" parts in the several tigures'of the. drawing.

The device, in the n'elerred construction shown. consists ol" a g ass tube which is bent so as to provide the intake. arm the 'dis-l charge arm l, ll|e. substantiall U-shape'd beud(", connecting A and B, the. suction ii Pat-entedlllay 19 11.

arm D, and the U shaped bend E making the portion D continuous with the portion B. The end ofthe suction arm D is provided with the compressible, preferably rubber, bulb F. The bend E on its lower side is formed with a discharge opening G. Preferably the-intake arm is formed at, its intake end with the U-shaped bend H, the opening I being fiaring'and provided with the ri J. i

, The device so constructed is used, for example, for decanting the cream from amilk bottle, in the following manneriThe intake end of the siphon is insertedinto themouthi of the bottle K until the rim J is at, say the milk level, indicated by the dott'ed'line in the bottle so deeply. The bulb F is'com-' pressed. A ves'selL is placed under the discharge opening G. The user then places his finger over the opening G, so as to cover thesame, and releases the bulb. The rarefication of the air in thetube starts the flow of the cream through the siphon and out, of" opening 1:, which, of course, has been ancovered as soon as the bulb F is allowed to expand. It will be seen thatthefiow fromv the bottle is downward into the intake end of the siphon, so that there is little tendency to disturb the milk. The rim J also tends to preventany flow of the milk into the mouth ,of the siphon and furthermore aids the e e m accurately locating the mouth at the esired level.

'lheudevicc can be made entirely of glass and can be made, as shown, so that there are nosharp corners, projecting edges or pockets, which would make-the device ditiieult to keep clean. .13 y properly proportioning the size of the bulb l ind-elation to the volumetriccontents of the tube and the length of the intake, discharge and'suction arms, it;

will be possible to obtain suction enough to I always startthe flow, while making itimpossihle that. any of the decanted liquid should be. drawn up through the suction a'rln into the bulb. Thus the volume-of the tube from the bend C to the bulb F should be a least as great as that of the bulb F.

'l he device may be made very cheaply, as it. may consist simply of a glass tube and a rubber bulb. The tube may be washed by removing the bulb and running water through'lt.
